FileSystemManager::loadSkatResults | end - not found file - /efs/a0504a63e1595b88/skatmaster/results

What Happened#

2026-04-22 13:17~13:20 UTC 사이 cupixworks-capture-postprocessor-agent에서 5건의 에러가 발생했다. postprocessor agent가 EFS 상의 skatmaster/results/capture_alignments.json 파일을 읽으려 했으나 파일이 존재하지 않아 처리에 실패했다. 5건은 3개 팀(lemartec, futsu, whitingturner/rsconstruction), 2개 리전(us-west-2, ap-southeast-1)에 걸쳐 서로 다른 capture에서 발생했으며, 각 실패 후 BaseService::handlingMessageErrors에 의해 SQS 메시지가 에러 처리되었다. 대표 에러인 capture 683964의 경우, upstream에서 이미 에러 코드 AGT1201이 설정되어 있었고 SKAT이 alignment 결과를 생성하지 않았음에도 postprocessor가 트리거되었다.
